The standard code, using a coded character set consisting of 7-bit coded characters (8 bits including parity check), used for information interchange among data processing systems, data communication systems, and associated equipment. The ASCII set consists of control characters and graphic characters

American Standard Code for Information Interchange

ASCII

A standard code used for information exchange among data processing systems, data communication systems, and associated equipment. ASCII uses a coded character set consisting of 7-bit coded characters. See also Extended Binary Coded Decimal Interchange Code

Pronounced Ask-Kee - American Standard Code for Information Interchange is an ANSI standard seven-bit code that was proposed in 1963 and finalized in 1968. The standard ASCII character set consists of 128 decimal numbers ranging from zero through 127 assigned to letters, numbers, punctuation marks, and the most common special characters. The Extended ASCII Character Set also consists of 128 decimal numbers and ranges from 128 through 255 representing additional special characters. The ASCII encoding scheme (or some variation) is used on most computer systems. Two of the exceptions are the IBM Mainframes and AS/400. For additional information refer to EBCDIC. For a table of ASCII and EBCDIC values refer to the following URL. http://www.simotime.com/asc2ebc1.htm>

American Standard Code for Information Interchange. A modification of the international code which has become a de facto standard (except for IBM which uses the EBCDIC code) for transmitting data. Uses seven bits plus a parity bit, and includes alphanumeric and control characters. ASCII must be converted to EBCDIC for uploading to IBM mainframes. ASCII terminals is often used to refer to asynchronous terminals such as those used in the Unix environment. IBM?s main ASCII terminal family is the 3164.

ASCII

An encoding scheme that is used to represent strings in many environments, typically on personal computers and workstations. Contrast with EBCDIC and Unicode

ASCII

American National Standard Code for Information Interchange

BCDIC

Binary-Coded Decimal Interchange Code. A 6 bit character representation used by most non-IBM-compatible mainframes in the 1950s through 1970s. cf. ASCII, EBCDIC.

binary

(1) Pertaining to a selection, choice, or condition that has two possible values (2) Pertaining to a system of numbers with a base of two. The binary digits are 0 and 1 (3) In DB2 for i5/OS, pertaining to a data type indicating that the data is a binary number with a precision of 15 (halfword) or 31 (fullword) bits

BINARY

A numeric encoding scheme used on a mainframe. The mainframe is a half-word, full-word and double-word centric system. Binary fields are 2, 4 or 8 bytes. For example, the number 10 would normally be stored in memory as x'F1F0'. If the number 10 is defined as BINARY (or COMP for COMPUTATIONAL) it will be stored in memory as x'000A' or 0000 0000 0000 1010. Refer to COMP> in this glossary or http://www.simotime.com/databn01.htm> for more information

binary data

(1) Any data not intended for direct human reading. Binary data may contain unprintable characters, outside the range of text characters. (2) A type of data consisting of numeric values stored in bit patterns of 0s and 1s. Binary data can cause a large number to be placed in a smaller space of storage

binary format

Representation of a decimal value in which each field must be 2 or 4 bytes long. The sign (+ or -) is in the far left bit of the field, and the number value is in the remaining bits of the field. Positive numbers have a 0 in the sign bit and are in true form. Negative numbers have a 1 in the sign bit and are in twos complement form

Byte

A string of 8 bits that represents one EBCDIC character. The IBM mainframe architecture is organized around the concept of the byte.

Extended Binary Coded Decimal Interchange Code. Coded 8-bit character set (giving 256 characters) used in IBM minis and mainframes, and SNA. One of two character codes used in IBM kit. See also ASCII, Unicode, BCDIC.

EBCDIC

Extended binary coded decimal interchange code. An encoding scheme that is used to represent character data in the z/OS, VM, VSE, and iSeries environments. Contrast with ASCII and Unicode

Pronounced Ebb-See-Dick. The EBCDIC character encoding set is used by IBM mainframes. Most other computer systems use a variant of ASCII, IBM mainframes and midrange systems such as the AS/400 use EBCDIC and were designed for ease of use or back level compatibility with punched cards. For additional information refer to ASCII. For a table of ASCII and EBCDIC values refer to the following URL. http://www.simotime.com/asc2ebc1.htm>

Extended Binary-Coded Decimal Interchange Code

EBCDIC

An encoding scheme that is used to represent character data in the z/OS environment. Contrast with ASCII and Unicode

extended binary-coded decimal interchange code

EBCDIC

A set of 256 characters, with each character represented by 8 bits

hexadecimal

Pertaining to a numbering system that has a base of 16

hexadecimal

A base 16 numbering system. Hexadecimal digits range from 0 through 9 (decimal 0 to 9) and uppercase or lowercase A through F (decimal 10 to 15) and A through F, giving values of 0 through 15

hexadecimal constant

A constant, usually starting with special characters, that contains only hexadecimal digits

hexadecimal string

In REXX, any sequence of zero or more hexadecimal digits (0-9, a-f, or A-F), optionally separated by blanks, delimited by apostrophes or quotation marks, and immediately followed by the symbol x or X

interchange code

An accepted convention for computer character representation. An interchange code typically defines several code pages. EBCDIC and ASCII are interchange codes

Unicode

A character encoding standard that supports the interchange, processing, and display of text that is written in the common languages around the world, plus some classical and historical texts. The Unicode standard has a 16-bit character set defined by ISO 10646. See also multibyte character set

Unicode

A character encoding standard that supports |the interchange, processing, and display of text that is written in the common |languages around the world, plus some classical and historical texts. The |Unicode standard has a 16-bit character set defined by ISO 10646

Unicode

(1) A universal character encoding standard that supports the interchange, processing, and display of text that is written in any of the languages of the modern world. It also supports many classical and historical texts in a number of languages. The Unicode standard has a 16-bit international character set defined by ISO 10646. (2) An international character encoding scheme that is a subset of the ISO 10646 standard. Each character supported is defined using a unique 2-byte code. See Extended Binary Coded Decimal Interchange Code, American Standard Code for Information Interchange

Unicode

A character set coding scheme, just as ASCII and EBCDIC are, but with the ability to represent all written human languages. The character code is 16 bits wide which yields up to 65,536 characters (compared to EBCDIC?s 256). The Unicode committee was set up in 1989, and included IBM, Apple, and Microsoft among its number.

Unicode

A standard that parallels the ISO-10646 standard. Several implementations of the Unicode standard exist, all of which have the ability to represent a large percentage of the characters that are contained in the many scripts that are used throughout the world
